Answer:
<u>The disadvantages of 'bio-magnification are:</u>
<u>Impact on Human Health</u>
Biomagnification makes humans more prone to cancer, kidney problems, liver failure, birth defects, respiratory disorders, and heart diseases.
<u>Effects on Reproduction and Development of Marine Creatures</u>
The toxic chemicals accumulate in the important organs of aquatic organisms that affect their reproduction and development processes.
For eg., the shells of the eggs of the sea-birds are very thin that might get crushed by the birds themselves during incubation. The toxic chemicals, mercury and selenium destroy the reproductive organs of aquatic creatures.
<u>Destruction of Coral Reefs</u>
Cyanide that is used in leaching gold and fishing is the main cause of the destruction of coral reefs. Coral reefs are the dwelling and feeding grounds for many sea creatures. Their destruction affects the lives of many aquatic animals.
<u>Disruption of Food Chain</u>
The chemicals and toxins which are released into the water bodies disrupt the food chain. The small organisms absorb the toxins which are eaten up by larger animals. These toxins, thus, get accumulated in the higher level of organisms.
Generally speaking:
Concentration of product(s)/concentration of reactant(s)
If the balanced equation has a coefficient of more than one, you would put the concentration for that compound to the power of that number.
For example:
A + 2B ---> C
K= [C]/[A][B]^2
